I think you are right there. If a station is not too greedy with their coverage and use good kit and maybe 5 - 20W or whatever it needs I think you make your
chances of staying on longer better. Sure you don't have the strong signal but you keep that signal out of areas where there might be less welcome listeners.

Always difficult to know but with more publicity of any kind there comes more unwelcome listeners as well. A double edged sword.
